Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
Hi
I am designing Circuit with nRF4122 - QFN package 48 pin, as per datasheet there is circuit for Trace/ PCB Antenna
But i am planning to use Chip Antenna and BAL-NRF02D3...
Hi,
I have a custom board someone designed with two SPI masters and one I2C master. We're now trying to enable the second SPI master and I'm running into errors because...
Hi all,
I am working on FOTA, my set up is with SDK15. I have followed the steps for DFU and i have used the secure_bootloader example, the thing is working fine, i can...
hi i have attached my gps+gsm module with nrf51 development kit and while reading an out put i wont be able to see any output , even with out put i dont know to to do debugging...
Hi,
I have completed all steps in the example at the following link https://devzone.nordicsemi.com/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader and all...
I am developing hardware for the nRF52840. After testing our firmware, we are going to need somewhere around 6,000-7,000 mAh to run our hardware for the time needed. We were...
Hi, all.
I used sd_ble_gap_addr_get() function to get a MAC address in the different example and the result was different.
I tested this example in SDK v14.2 and v15...
Hi,
The amount of information and reference documents available about Bluetooth qualification is overwhelming. It would be great if someone with this experience sheds some...
Do nRF8001 chip has its own internal linear regulator? or Does it need an external like the module created by Adafruit ( https://cdn-learn.adafruit.com/assets/assets/000/035...
Good evening all,
I'm trying to get my DK52 communicating with a CR95HF (this is a NFC controller with serial and SPI control interfaces), I'm using a breakout board - BM019...
Hi Sir, I use load switch circuit to control nrf8001's power. I found even the vcc of nrf8001 is empty, nrf8001 still works. That's not my expected result, I think nrf8001...
Hi ,
We know that the nRF8001 use the random static device address . I have the questions below :
A. Will the device get one new address after power on ? or is the address...
Hi,
I need to exchange data between 2 ble modules.
I'm using SKD 15.0.0 and first ble module is nRF52840, second ble module (esp32) acts as GATT server.
I have full...
Hi, I am trying to make nrf52832 as a UART certal. The service UUID and characteristic UUID of peripheral are shown as the following picture. They are all 128bit and quite...
